Aqara SynologyRackStationSA3400D

Synology RackStation SA3400D — enterprise 12-bay rackmount NAS with dual Intel Xeon controller nodes in active-passive HA configuration, delivering over 3,500/2,900 MB/s sequential read/write and minute-level failover. 8GB RAM. Sold without HDDs.

The SA3400D is designed for data-intensive applications in enterprise environments where downtime is unacceptable. Two controller nodes operate in active-passive mode — if the primary controller fails, the secondary takes over within minutes without data loss. Built-in software covers Snapshot Replication, Hyper Backup, and the Active Backup Suite for comprehensive protection. Storage capacity can be tripled by adding Synology expansion units without replacing the primary chassis.
